If I place an object into water and it floats, that means the object is what?

Less dense than water

100

What powers the water cycle process?

The Sun - heats up the water to evaporate

100

What process causes slow changes to the earth?

Weathering, Erosion, and Deposition 

100

Why do biotic factors need abiotic factors?

Biotic factors need abiotic factors in order to survive (ex. sunlight, oxygen, water)

What is the power source of the circuit?

Battery

200
What is the process of cooling a gas into a liquid called?
Condensation
200

What is the difference between weather and climate?

Weather changes day to day, while Climate is over a long period of time of 30 years

200

How is a delta formed?

Water drops off sediments at the end of a river into a larger body of water, causing the sediments to build up and make a delta
200

Why do some animals have sharp teeth while others have flat teeth? What are the functions of these teeth?

Sharp teeth are used to eat and tear meat, while flat teeth are used to eat plants and grass.

Why does a fish appear to be bigger when looking from above the water?

Refraction
300

What is the surface force that acts against a moving object?

Friction

300

What is the difference between Earth's rotation and Earth's revolution?

Earth's rotation is the spinning of Earth on its axis in 24 hours. 

Earth's revolution is the orbit around the sun in one year. 

300

What is the process of sedimentary rocks being formed?

Weathering breaks it, Erosion takes it, Deposition drops it off, Compaction presses it down together, and Cementation sticks it together.

300

Why do some plants have large leaves? What environment is this typically in?

In order to catch more sunlight to live. This is typically seen in rainforest because many trees are competing for light.
300

What is the difference between a conductor and insulator?

A conductor allows heat and electrical energy to go through, while an insulator does not. 

400

In order to separate sand from saltwater, I must use what?

A filter

400

What causes the sun's apparent motion to move across the sky? 

Earth's Rotation

400

What is the difference between natural gas/oil and coal?

How can you remember how fossil fuels are made?

Natural gas and Oil are made from ocean animals and Coal is made from swamp plants.

THOP: Time, Heat, Organic Matter, and Pressure

400

What is a similarity and a difference between a nymph and pupa? 

How many stages do incomplete and complete metamorphosis have?

Nymph looks like a smaller version of an adult, while the pupa does not look similar to an adult. They both eat and grow after they hatch from the egg.

Complete metamorphosis life cycle has 4 stages that include larva and pupa. Incomplete metamorphosis life cycle has 3 stages that include nymph.

What is the difference between a dependent and an independent variable?
Independent variable is the factor being tested while dependent variable is the factor being measured
500

What material is being described? 

solid, non-soluble, more dense, non-magnetic, conductor of heat/electricity 

Copper

Where is the sun's position at 10:00 am, and which direction would a shadow be casted at?

The sun's position is located northeast while the shadow is located southwest.
500

What is the process called when you see water droplets on the side of a water bottle? Describe the process.

Condensation - when gas cools down to a liquid
500

What causes animal and plant adaptations? 

The environment

If I add sugar to warm water, what two physical properties of the sugar will stay the same?

Taste and Mass
